Magnesium chromate and dicromate.-A magnesium chromate is produced by reacting in presence of water an alkali or alkaline earth chromate with a magesium salt of an acid whose alkali or alkaline earth salt is less soluble than the magnesium chromate produced. In the examples, calcium chromate is boiled with magnesium sulphate, the reaction being effected in a reflux apparatus or under pressure; sodium chromate and magnesium chloride solutions are mixed, preperably by pouring the sodium chromate gradually into the magnesium chloride solution, and the mixed solution is evaporated in vacuo at 30- 35‹ C., the sodium chloride crystals being removed, after which magnesium chromate crystals form; sodium chromate is reacted in a similar manner with magnesium sulphate, the evaporation being at about 40‹ C.; sodium dichromate and magnesium chloride solutions are mixed and the solution is evaporated at a temperature not above 40‹ C.; and sodium chromate sulphuric acid and magnesium sulphate are reacted together hot and the sodium sulphate is separated on cooling.

Abstract: 1,204,065. Colour television tubes. TEXAS INSTRUMENTS Inc. 18 March, 1968 [31 March, 1967], No. 12916/68. Heading H1D. [Also in Division H4] A system for providing a display in three colours in response to respective colour signals comprises means for generating light of a selected colour in a predetermined pair of zones on a viewing screen, said zones being partially overlapping and offset from one another in one direction along the screen, means for repetitively sweeping both of the zones together across the screen to form respective sets of raster lines extending transversely to said one direction with the overlapping portion of said zones providing a third set of raster lines interposed between said respective sets of raster lines, the brightness of the third set being substantially equal to the average of the brightness of said respective sets, means for changing the colour of the light generated on successive sweeps, and means for modulating the intensity of the light generated, so that each line sweep produces three lines of the same colour on the screen. As shown in Fig. 1, the display device 11 includes a glass face plate 13 coated with a mixture of phosphors 15 which emits light of different colours in response to impinging electrons of different energies as controlled by a staircase voltage from high voltage switch 17 operated by the horizontal sync. signal applied at 72. A pair of electron guns 21, 23 provide electron beams 31, 33 which are offset from one another but have a cross-section, e.g. figure-of-eight, provided by suitably shaped grid apertures or by vertically defocussing the beams such that they partially overlap, Fig. 1A, and three raster lines are defined in which the electron distribution for the centre line is approximately equal to the average of the upper and lower lines. As arranged for the NTSC system, the luminance or Y signal is obtained at 41 from the received signal and the colour subcarrier is synchronously demodulated at 61 to provide the chrominance signals R-Y, G-Y, B-Y. The luminance and chrominance signals are combined in respective summing networks 65, 67, 69 to produce R, G and B colour signals which are supplied to an electronic gate 71 controlled by the sync. pulses from 72. Gate 71 provides a pair of line sequential control signals on leads 75, 77 with a one-line time displacement between the signals, the signal on lead 75 being delayed by one line sweep period at 79 so that the output of the delay line 79 contains information relating to the same colour as that carried by lead 79 but taken from the preceding line. The output of delay line 79 and the signal on line 77 are supplied to the upper and lower guns 21, 23 respectively and the scanning is preferably arranged so that the line formed by the upper gun during each scan falls on top of the line formed by the lower gun on the preceding sweep.
